Q310GNH kila

ʻōlelo pinepine ʻia e ka genericized trademark COR-TEN steel a i kekahi manawa i kākau ʻia me ka ʻole o ka hyphen e like me corten steel, he hui o nā mea kila i kūkulu ʻia e hoʻopau i ka pono no ka pena, a hana i kahi hiʻohiʻona paʻa e like me ka ʻōpala inā ʻike ʻia i ka lewa. no kekahi mau makahiki.
Ua loaʻa i ka COR-TEN kumu ka inoa maʻamau A 242 (COR-TEN A) mai ka hui maʻamau o ASTM International. ʻO nā māka ASTM hou aʻe he A 588 (COR-TEN B) a me A 606 no ka pepa lahilahi. Hoʻohana like ʻia nā alloys a pau.

Ke hoʻohālikelike ʻia me ke kila kalapona, ʻoi aku ka maikaʻi o ke kila Q310GNH i ka corrosion i ka lewa. Ke hoʻohālikelike ʻia me ke kila kila, aia wale nō nā mea hoʻohuihui, a ʻo ka huina o ka phosphorus, keleawe, chromium, nickel, molybdenum, niobium, vanadium, titanium, a me nā mea ʻē aʻe o nā alloys e like me ke kila weathering he hapa wale nō.
